The present invention refers to apparatus for removing gases from feed water, and more particularlyto feed-water purifying apparatus whereby the gas is removed from the purifier by special means. p

The purpose of the present invention is the purification of feed-water by heating it with live steam, and a further purpose is the automatic release of the mixture of gas and steam. which accumulates in the purifying vessel.

My invention will be best understood in connection with the accompanying drawing which-illustrates one of the various forms in which it may be embodied, and in which the single figure is a vertical section through a boiler equipped with a device according to my invention.

. Referring to the drawing,

1 is a boiler, 22 the purifying chamber,

consisting of vessel 22 whichis angular in vertically longitudinal section and preferably has a relatively broad flat bottom. The vessel 22 is open solely at its end 22 and near this end is a bonnet 16 provided with a non-return flap 17 which permits steam to enter into the chamber 22 but checks it in the reverse direction. The feed water enters through pipe 18, rises in the short leg in the casing 22 to the highest point of the bottom thereof, and flows down on the slightly inclined bottom of the longer leg of the casing 22 on which it forms a thin broad layer. The heating steam for the feed water enters past flap 17 of the bonnet 16 and flows counter to the feed .water, thereby purifying it in well known manner. The mixture of gases and steam is conductedoff through the tube 19 which is arranged at the highest point of the easing 22. Opening and closing of tube 19 may be effected automatically by means of an angular lever 20 arranged withinthe casing non-return valve 20?", and the arrangement is suchwthat-th-is' valve is opened when the.

long as. no feed water is supplied through tube 18, valve 20 'being kept down by the weight of lever 20,plate 21 and the water column above21. If, however, feed water is supplied, for instance, byopening valve 32, plate 21 will be lifted, valve 20"v opens andthe mixture. of gas and steam can escape. from .22. iAt-the same time, live steam will enter the vessel22 through check valve 17 'and purify the feed water, as described above. I

It is, of course, understood thatprovision is made for preventing any unnecessary waste of the steam and gas mixture leaving past valve 20 during the purificationperiod, as e. g. by suitably dimensioning the various parts of the device, or by utilizing that mixture for operating auxiliary machinery, etc.

What I claim as my invention and desire to secure by Letters Patent of the United water supply for said chamber, check valve controlled means for introducing live steam directly from the boiler into said chamber to drive the gases out of the feed water in said chamber, an outlet in said chamber for said'gases, a valve in said chamber con-- trolling said outlet, a valve in said chamber controlled by the flow of the feed water, and aconnection between said last two valves for causingthem to open simultaneously.

, 2. In a device of the class described, a boiler, an arched tube mounted in said boiler having both ends extending below the normal water-line of said boiler,vone of said ends being open and the other end being connected to'a feed water supply, a check valve controlled opening for admitting steam into said tube from the steam chest of the boiler to drive out the gases and precipitate the salts from the feed water 7 ously.

flowing through said tube, an outlet for said gases extending through the wall of the boiler, a valve controlling said outlet, a valve controlled by said feed water supply, and a connection between said last two valves for causing them to open simultane- 3. In a device of the character described, a boiler, an arched vasselhaving one end open and extending below the normal water level of the boiler, and having the other end connected to a feed water supply, a check valve for admitting steam from the boiler into said vessel "for the purificationof feed Water passing through the vessel, an outlet valve for the steam and the gaseous waste products from said vessel, a combined valve and baflie plate member between said vessel and the feed-water supply, and means connecting said plate member with said outlet valve, said means being adapted to' open the outlet valve Whenever the flow of feed water opens the combined valve and bafile plate member.

4; A device of the class described, comprising a boiler, a feed-water chamber, a feed-water supply for said chamber, means including a non-return device for introducing live steam directly from said boiler into said chamber to drive the gases out of the feed Water in said chamber, an outlet for said gases leading from said chamber, a valve controlling said outlet, and means in said feedwvater supply responsive to the flow of feed water and connected to said valve, for causing the latter to open when the feed-water flows.
